jQuery – A Simpler and Better JavaScript Solution

An Introduction to jQuery

jQuery is a form of JavaScript which makes it simpler for designers to modify HTML events, animations and other interactions that may be present on a web page. These can be done by the addition or subtraction of style sheet handlers. The relevant handlers are HTML classes or IDS and they are specified in style sheets to inform the browser of the positioning and style of HTML elements on a web page.

With the help of jQuery, web site designing firms can edit these handlers to documents on specified events very easily. These specified events can be any action such as hovering the cursor on a link, etc.

jQuery is also particularly useful in simplifying the AJAX applications. AJAX applications are client related web development techniques which are used to create interaction based web applications. AJAX too utilizes HTML and CSS to modify the style and layout of the website through the user’s inputs.

What Makes jQuery Work

The biggest advantage of using jQuery is that unlike other JavaScript libraries and interactive applications, it does not shield the web site’s content from search engine spiders. Flash and other application end up shielding a lot of content in a website if the JavaScript of the web page is not enabled.

These applications are improving with time at being recognized by search engines but they do not match jQuery’s functionality. jQuerys brevity and cleanliness in code also makes it a lot easier to download than say, downloading a Flash based web page.

The Advantages of jQuery:

  1. It is almost five times lighter than regular JavaScript code. Thus it is the library with the least amount of vestigial code. A leaner development means smaller sized files with lesser load times.

  2. It is replete with plug-ins and thus, many elements can be added which increase the appeal of the webpage. The large and interactive jQuery community also provides solutions for bug fixes and loose coding.

  3. Website designing firms can implement jQuery easier than they can other applications.


  4. There is also detailed information and examples given for using the library on a web site.

  5. It is the most popular JavaScript library and works well with all browsers

  6. It is free and open sourced and is simple and powerful enough to design dynamic websites.

  7. Despite JavaScript being turned off in a browser, web page elements will still show up.

  8. AJAX is made more lucid.

  9. Commands can be linked in order to have flow within a website.

  10. Animation applications which are built in can be used as commands.

  11. Reduces the number of keystrokes thereby making user experience better.

  12. jQuery performs Flash’s functions in a more SEO friendly manner.

Understanding jQuery

jQuery is used by JavaScript to locate a specified HTML element. A tag within a page would have a certain style sheet which could be animated to scroll slowly. This would be useful for adding a news ticker application to the web page.

It is also helpful in finding HTML elements held within a specific CSS ID class and other sub-elements can also be obtained. The elements can then be reset to create another specific CSS class. This can result in alternate styles which can be useful for table presentations, where the background color of each column is alternated between.

A few jQuery effects and animations

Whenever the user interacts or performs an action on a certain HTML element, then jQuery is called upon to and its effects and animations are put to use. This action is anything such as a mouse click or hovering over an element or other such functions. jQuery can scroll, fade in, fade out, fade to, zoom or draw close. It can also show or remove a toggle or slide up or down or between toggles. There are also animations for stop and to queue while a whole different set of effects for loading, resizing, scrolling and dragging.

Online shopping sites are making a lot of money with the use of web-based applications to sell products, collect payments an arrange delivery. The only work left to do is pack and send the boxes.

Smart Investors: Three Real Estate Scams You Should Never Fall For

“Honesty is a very expensive gift. Do not expect it to come from cheap people.” –Warren Buffet

 There has never been any doubt that succeeding in real estate takes hard work, determination and commitment.

 It is not some get rich quick scheme as some have been misled to believe. It takes laborious work to see any real results and unfortunately, not all individuals in the industry are prepared for that kind of dedication just to succeed. Resultantly, some would give up with the belief that they are not cut out for that kind of line of work while the rest would resort to sleazy machinations just to guarantee a sale.

 From there, all sorts of scams and fraudulent schemes are cooked up and it is unfortunate that there are investors (especially novices and first-timers) who would be none the wiser and would buy into the scam. No doubt, the real estate industry is a sector that can be extremely profitable. But as it was stressed above, it requires hard work and unfortunately, some people a…

AMOLED display coming to Samsung Galaxy Tab range

This is a guest post by Erica about the arrival of AMOLED display to Samsung Galaxy Tab range.Samsung could be transplanting a seven inch AMOLED screen into an upcoming addition to its Galaxy Tab range of tablet computers.

You may have experienced an AMOLED display in a small portable device before as Samsung, Nokia and HTC have all used them in smartphones to date. However, the expense of producing AMOLED screens has prohibited them from appearing on larger devices like tablets, until now.


The seven inch Galaxy Tab was launched last year but an update with an AMOLED screen would be most welcome, cutting energy consumption and improving colours and contrast ratios across the board.


The rumours about this device state that it will run Android 3.0, feature a three megapixel camera on the rear, a two megapixel snapper on the front and have a display resolution of 1024x600 which is not bad for a device of this size.


The hardware powering the new Galaxy Tab will consist of a 1.2GHz processor w…

Building Blocks for Virtual Businesses : Key technological systems you must have to succeed in the remote business world

This is a guest post by Ripley Daniels about "Key technological systems you must have to succeed in the remote business world.

Whenever I tell friends I had a tough day at the office, they laugh at me. That's because they know I don't really have an office. I work very hard but I work for a company that is completely remote. Only a few of my co-workers ever go into an office at all and when they do, it's only for short periods of time. Our "office" is a virtual one. To us, the traditional office workplace is a thing of the past, alongside Tyrannosaurus Rex, the slide rule, and telephones where you stick your finger in a hole and turn a dial.
Unfortunately, none of this prevents me from having tough days. I still have them. But the reasons have nothing to do with the fact that my co-workers and I don't have a brick and mortar edifice that we can use to plan, strategize, hold our meetings, make presentations, discuss sensitive business topics, build relatio…
